The only create_directory call is in
bin/schroot-mount/schroot-mount-main.cc
which creates mountpoints inside the chroot.  Are you mounting
in a directory path which has more than two levels nonexistent?
It might be that mkdir is failing due to create_directory not
behaving like "mkdir -p", in which case we should add the
functionality.

Regarding errors, the useless error is coming from boost.  I'll need
to reproduce it and see what it's doing, and then file a bug against
boost if it's at fault.
